Java

No slides, no schedule. We're meeting up for a relaxed ZurichJS summer meetup with drinks, barbecue, and people who build things. If you’re shipping an AI tool, a vibe-coded side project, a SaaS product, or an existing app that could use a better business model, bring it along. We’ll hang out, compare notes, and brainstorm how to turn useful software into something that actually makes money. Let's get the bbq going with beers and geeks. Important: this is a potluck edition. Bring your preferred barbecue option (and maybe some extra to share if you want), some picnic blankets or picnic chairs, anything that you'd normally bring to a picnic. We're a big family at the end of the day 🫶 **Agenda** * None whatsoever **👉 [Event page](https://zurichjs.com/events/june-2026) \| Location Josefwiese** **About the organizers** * **[Bogdan Ilie](https://www.linkedin.com/in/ilie-bogdan/)** is a user advocate.

Hallo liebe Java User Group Mitglieder! Diesmal haben wir zwei Bonner Kollegen zu Gast: * Martin Stoller: **Backend-Performance in Hochlast-Systemen: Lösungsansätze aus dem Data Engineering** * Andreas Monschau: **Zehn goldene Regeln, um dein Softwareprojekt zuverlässig zu ruinieren** Wir freuen uns euch zu sehen (virtuell oder vor Ort). Dank an [codecentric](https://www.codecentric.de/standorte/nuernberg) für Location, Bier und Pizza! ================= Viele Hochlast-Systeme beginnen als kleine, unscheinbare Prototypen - gebaut mit bewährten Mitteln wie relationalen Datenbanken, objektorientierter Business-Logik und klassischen Request-Response-Architekturen. Doch was passiert, wenn diese Systeme plötzlich nicht mehr Tausende, sondern Millionen von Requests bedienen oder Terabytes an Daten verarbeiten müssen? In der Praxis zeigt sich häufig: Klassische Optimierungen wie Caching, horizontale Skalierung oder effizientere Algorithmen stoßen irgendwann an ihre Grenzen, weil sie innerhalb desselben Paradigmas bleiben. Dieser Vortrag zeigt, warum echte Skalierbarkeit oft ein Umdenken erfordert. Anhand eines durchgehenden Praxisbeispiels wird schrittweise demonstriert, wie sich ein System von einer latenzoptimierten Request-Response-Architektur hin zu einem durchsatzoptimierten, analytischen System entwickelt. Dabei werden zentrale Konzepte aus dem Data Engineering greifbar gemacht - darunter Precomputation, Batch Processing, deklarative Verarbeitung und Denormalisierung - und in den Kontext klassischer Backend-Entwicklung eingeordnet. Die Teilnehmenden lernen, typische Grenzen traditioneller Architekturen zu erkennen und erhalten ein alternatives Denkmodell, um High-Throughput-Systeme gezielt und nachhaltig zu skalieren. ================= Softwareprojekte sind chaotisch, anstrengend und voller Überraschungen. Und ganz ehrlich: So soll es auch bleiben. Ordnung würde ja nur den Spaß verderben. Trotzdem gibt es immer wieder Menschen, die glauben, man könnte Projekte wirklich zu Erfolg führen… unglaublich, oder? Damit dir so etwas nicht passiert, zeige ich dir in diesem Vortrag, wie du ein Softwareprojekt in 10 einfachen Schritten zuverlässig an die Wand fährst. Die „goldenen Anti-Pattern für maximalen Projektschaden“ entstammen jedoch nicht meiner Fantasie, nein, sie werden in der Realität täglich mit beeindruckender Konsequenz praktiziert. Und das Beste: Sie wirken nachhaltig. Manche dieser Muster entfalten ihre volle Zerstörungskraft erst Monate später. Nachdem du alle Regeln kennengelernt hast, kannst du selbst entscheiden: Möchtest du sie weiterhin anwenden, oder vielleicht doch etwas verändern? Solltest du allerdings inspiriert sein, eines dieser Anti-Pattern künftig noch konsequenter zu leben… dann sollten wir uns nach dem Talk dringend unterhalten. ================= Dein Vortrag bei der Java Usergroup Nürnberg! Hast du dich in letzter Zeit in deinem Projekt oder privat mit einem interessanten Thema beschäftigt? Vermutlich ist das nicht nur für dich selbst interessant! Hast du Lust, selber einmal einen Vortrag bei der Java-Usergroup Nürnberg zu halten? Wir sind nicht nur auf Java-Themen fokussiert, sondern beschäftigen uns gern mit und um alles über Software Entwicklung und IT. Wir wollen bei der JUG nicht nur bekannten Speaker\*innen eine Plattform geben und die neuesten State-of-the-Art Technologien vorstellen. Wir freuen uns auch besonders, wenn wir Themen aus unserem technologischen (Arbeits-)alltag Raum geben zu können. Melde dich gerne bei uns, wenn du dazu Lust hast, wir geben wenn gewünscht gerne auch Hilfestellung bei der Vorbereitung!

Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for speakers for our Monthly Meetups!

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD

We're going to GameArena! We'll be in-person at the GameArena Gateway for our monthly COGG Prototype and Play event. Come to play and showcase your games! We're back in the upper levels of the catwalk area. It'll be packed with lots of camaraderie playing your game(s) and other's games on the 2nd floor. Light snacks and water provided but you can buy food and drinks at the bar (alcoholic drink ID required). [www.game-arena.co](http://www.game-arena.co/) **Attendees:** Don't have a game to show? Not a problem! All are welcomed and invited from all ages and backgrounds. The more we can have to play test our games is all the better! **Developers:** Do you have a game that you would like to get critical feedback on? Would you like an excuse to work on a game with other talented artists, programmers, musicians, designers, and writers? Digital, table-top, non-experienced developers, and the like are welcomed! We'll provide signage for your game to help others learn more about your work. Wifi, outlets, tables, and seats (though standing tables also) are available. Come to the Prototype and Play workshop to collaborate and meet local game developers for an evening of epic and raw game play fun! Play works-in-progress, show off your own game, work with others to add polish to a game, or even lend your talents to other fellow developers. For this event, light snacks from the bar and water will be provided!
